The

,cam slot 21 ,is so shaped that when the fingers 12 are dra'wn hometowards the box carrier 1, there is a period of rest. during which suchcarrier is reciprooated for the pressing or completing operation of theturnover. Further, a ;suitable cam 22 on; the power shaft 16 may operateone limbv of, a

bell-crank lever 23, the other limb of which is attached toa secondbell-crank lever 2& (see particularly Figure 5.), adapted to actuatetheslide 6 ofthe carrier 1. i y

The power shaft 1.5.,may1be driven e f r a pulley 25 by way of a. onerev0luti=onclutch 26 (Figure 1-) operable by foot mechanism,

The timing of the parts is such that" the slidable; frame 11, is firstlymoved jtowa'rds r the carrier 1, the fingers passing, over the side wallagainst the :base'; or horizontal limb, During the operation of placingor positioning the box the projecting paper edge is brought into contactwith the ex; tremities 13 of the fingersan'd' is bent substantially atrightangles tothe wallofthe box, The apparatusis then 'sje't; inoperation,- the slidable frame '11 causing thefing'ers ion web and endwall 7 to move the already bentpaper edging i'n V wardly,' folding vit"on to the inner face of he box, the cip c ry .mo m ntofflw carrier. 1securelysealing i't5 and the fingers are then withdrawn.

angularly related sides, a relatively fixed wiper element, a fingercarrier having angularly related sides corresponding with those of thebox carrier, fingers carried by said sides of the finger carrier, meansto move said finger carrier toward and from. the box carrierlongitudinally thereof so that the fingers pass over the wiper elementand partly over the box carrier, and means to impart relativereciprocating lateral movement to the said carriers to cause saidlingers to move toward and'from said sides of the box carrier. 3. Inapparatus for covering boxes, a bo carrier open on one side and .havingangularly related sides, a relatively fixed wiper element, a fingercarrier having angularly related sides corresponding with those of thebox carrier, fingers carried by said sides of the finger carrier, means,to move said finger carrier toward and from the box carrierlongitudinally thereof so v that the fingers pass over the wiper elementand partly over the box carrier, and means to impart lateralreclprocatmg movement to the box carrier to cause said sides thereof,

to move toward and finger carrier. r a

4. In apparatus for covering boxes, a box carrier and a finger carriereach having two angularly related sides, said box carrier befrom thefingers of the 7 ing arranged. for lateral movement toward and from, thefinger carrier in a plane, which -atan equal'angle to each of said sldesof said finger carrier, said finger carrier 7 being arranged forlongitudinal movement toward and from the front end of the box carrierto pass the fingers partly thereover and withdraw the same therefrom.

5. In apparatus'for covering boxes, a box carrierand a finger carriereach having two angularly related sides, said box carrier bemg arrangedfor lateral movement toward and from the finger carrier in a plane whichis at an equal angle to eafch'of said sides".

' of said finger carrier, saidfinger carrierbeing arranged forlongitudinal movement toward and from the front end of thebox carrier topass the fingers partly thereover and withdraw the same therefrom, and awiper'arra-nged for contact with said finger during such movement of'thelatter.

6. In apparatus for covering boxes, a

supporting, frame, a box carrier open on one side and having angularlyrelated sides, O V

means mounting said boxcarrier on said frame for lateral movement ofsaid carrier ,in aplane at an equal angle to each of saidsldes of saidcarr1er, means to lmpart such movement to such carrier, a wiper elementmounted on said frame and arranged at the front side of said boxcarrier, alfinger carrier having angularly relatedf sidescorrespondingto those'of said box carrier,

fingers on said finger carrier, means mount lng said finger carrler 'onsaid frame for,

reciprocating movement of said finger,

carrier toward and from said wiper and the l front side of said boxcarrier to "pass said fingers over and from saidwiper and said sldesofthe box carrler, and'means to impart such movement to sa1d finger,carrler'.

.7. In apparatus for coveringboxes, a 'box' carrier element and a paperedge turning element,said elements being arranged for relative lateralmovement and also for rela-' tive movement longitudinally over said boxcarrier element and meansto impart such movements successively to suchelements.
